PWS-505P-1H Supermicro 500W 1U Server PSU

High-Efficiency 1U Server Power Supply Module for Dense Rack Power Delivery with the PWS-505P-1H

The PWS-505P-1H is a 1U, 500W AC power supply module designed for Supermicro server platforms where predictable power delivery, high conversion efficiency, and serviceable replacement logistics are required. As an 80 PLUS Platinum unit, it reduces wasted power and heat load in dense racks, supporting stable CPU and memory power rails without oversizing the chassis power envelope.

For systems engineers, the PWS-505P-1H provides PMBus 1.2 digital monitoring and control to integrate PSU telemetry into platform management workflows, enabling health status, power draw visibility, and proactive maintenance. Standard server-side outputs include a 24-pin ATX connector and an 8-pin +12V CPU connector with detachable 4-pin section, aligning with common 1U board layouts and simplifying spares management. Protection features such as OCP, OVP, UVP, OTP, and SCP help maintain uptime by isolating fault conditions, while operation from 0–50°C supports typical data centre thermal profiles.

Why Choose the PWS-505P-1H?

The PWS-505P-1H is an effective choice for single-supply deployments and as a replacement PSU in compatible Supermicro 1U chassis, balancing power density with operational efficiency. It fits environments that prioritise controlled power budgets, low heat output, and straightforward field serviceability, while providing the monitoring interfaces expected in enterprise server power architectures.

Supermicro designs power subsystems around data centre integration, focusing on electrical stability, long-term component reliability, and consistent mechanical fit across validated chassis families. This engineering approach supports standardised maintenance processes and reduces risk during fleet refreshes and in-rack replacements.

Key Applications:

• 1U server PSU replacement and spares stocking
• Non-redundant compute nodes
• Edge and branch office rack servers
• High-efficiency rack power standardisation
